How to Find Minimum Leaf or Node Value from Tree - Java

Java Programming

Node Class
public class Node { public int id; public String data; public Node leftChild; public Node rightChild; Node(int id) { this.id = id; leftChild = null; rightChild = null; } public void displayNode() { System.out.print("( " + id + ", " + data + " )"); } }

Find minimum leaf method in binary tree
public Node findMinimum(Node node) { if (node.leftChild != null) { return findMinimum(node.leftChild); } return node; }

Case for show minimum leaf value from the tree int choice = getChar(); switch (choice) { case 'n': Node minNode = theTree.findMinimum(theTree.root); System.out.println("Minimum node value is " + minNode.id); break; }
